Patented Apr. 7, 1942 WINDOW UNIT SIDE WING CONSTRUCTION Burdell S. Williams, Dayton, Ohio, assignor to Chrysler Corporation, Detroit, Mich., a corporation of Delaware Application May 6, 1940, Serial No. 333,516

3 Claims. 401. 98-94) The presentinvention relates to the construction of side wings for blocking the openings left between the ledge and sides of a window frame, the bottom of the lower sash of a vertically movable window and the sides of a window ledge air conditioning unit placed on the ledge of a window. The present invention is an improvement on existing structures for blocking the openings at the sides of the unit and may be used in conjunction with any air conditioning unit of the foregoing type which is smaller than the opening in which the unit is placed, but it achieves particular utility in connection with a unit mounted in accordance with the disclosure of my copending application filed concurrently herewith, Serial No. 333,515.

In particular, the invention comprises a folded or plaited member which may be expanded or contracted to accommodate different sizes of openings whereby the side wings may be manufactured in quantities for use in connection with many different sizes of windows. Specifically, the invention comprises an air impervious member having reentrant folds or corrugations, the member being rigid enough to maintain its shape in use but being relatively yielding to longitudinal compression or extension so as to be readily fitted to various sizes of window openings. In connection with the foregoing it is an advantage of the present construction that the side wing may be folded, rolled or compressed into a very small space so as to minimize the size of the carton required to accommodate the unit and the appurtenances thereto.

The present invention may be more readily understood by reference to the accompanying drawing wherein like numerals refer to like parts throughout.

In the drawing, Fig. 1 discloses a window ledge air conditioning unit in the position of use and having the present invention associated therewith;

Fig. 2 is a horizontal section taken substantially along line 2--2 of Fig. 1 looking in the direction of the arrows;

Fig. 3 is an isometric view of a modified form of side wing;

Fig. 4 is a similar view of another modified form of side wing; and,

Fig. 5 is a similar view of another modified form of side wing.

Referring to Figs. 1 and 2, there is disclosed a window frame I0 in which is provided an upper window I I and a lower, vertically movable window I2 having a lower sash member I3. The window ledge type air conditioning unit I4 is supported upon the window ledge I5 and is shown as attached to a bar It by a clevis strap H, the bar I6 being pivotally mounted upon a pivot post I8 fastened to lt-hetop of the window'ledge near the right lower corner of the window opening. A strap I9 is suspended from a hook substantially vertically above the post I8 and is provided with a hook 2| at its lower end which may be engaged with an eye 22 fastened to the unit at the upper left edge thereof. The bar I6 and strap I9 provide means whereby the unit may be swung into the room in accordance with the disclosure of the aforesaid copending application. It'is to be noticed that the strap I9 is shorter than the distance between hook 20 and eye 22 so that the outer edge of the unit is raised clear of the window ledge to permit swinging movement, and that the post I8 is provided with a lever 23 and cam 24 by means of which the right side of the unit may be raised clear of the window ledge. As shown in Fig. 2, a pair of straps I9 and a pair of eyes 22 are preferably provided. Also, Fig. 2 shows a condenser air deflecting hood 25 which is hinged at 26 so as to be capable of being pivoted onto the top of the unit to permit swinging thereof through the window opening when the window I2 is raised.

The present invention comprises a pair of side wing members 3Il,one of which may be mounted at the right side of the unit and remain fixed in position during swinging of the unit, and the other of which is mounted at the left side of the unit and may be removed to permit swinging movementof the unit. Each member -30 'comprises a plurality of verticalpanelstl hingedly connected together as by means of reentrantly folding or plaiting a fiat sheet of material. The member may be shipped in collapsed state and then opened to the desired extent at the place of use so as to fit within the sash guides with the folds thereof extending vertically between the window ledge and the bottom. sash I3. The ma-,

terial may be of sufiicient resiliency to be stretched to a length greater than the desired space, so that when inserted in the space it will exert pressure against the side of the unit and the side of the window opening. Preferably, a strip of sponge rubber 32 is placed on the window ledge and another strip of sponge rubber 33 is placed between the sash I3 and the top of the member 30 so as to seal the edges of the opening. It is readily obvious that the member 30 at the left side of the unit may be compressed and extracted from the space it occupies during use in order that the unit may be pivoted into the enclosure. 7

The material of which the members 30 is composed may comprise thin metal stock decorated to harmonize with the room, or plated with a noncorrosive metal, or may comprise any of certain fibrous or plastic materials which have the desired characteristics described previously. In addition, the material may be such, as in certain plastics, as to be translucent or transparent so as to permit the passage of light through the material into the room.

The modification disclosed in Fig; 3 showsvertical panel portions 3| provided with pintel receiving bends 35 at their edges which are adapted to receive pintel members 36. Preferably, the hinges so formed are reversed in position as shown in Fig. 3 so that alternate-hinges are in side of the bends and the other hinges are outside of the bends of the side wing so that the side wing may be collapsed to a certain extent by reverse foldingbut, when stretchedout to its fullest longitudinal direction, will resist compression longitudinally.- Preferably, the material is resilient so that the vertical panel portions 3| will bend thereby permitting compression longitudinally into a smaller space than would normally be occupied in order that the side wing ,will exert pressure against the side of the unit and the side of the window opening.

In Fig. 4 the side wing is shown as comprising vertical panel portions 3| of very narrow width and at the junctions ofreversely curved portions 40, the side wing being thus a corrugated panel which may be rolled upon itself during shipment and may be collapsed to more or less extent 1ongitudinally in order to accommodate difierent sizes of openings. In the modification of Fig. 5 the vertical panel portions 3| are similar to the form shown in Figs. 1 and 2, exceptthat the bends between the panel portions are formed around vertical, reinforcing rods 45 which give vertical rigidity to the side wing. The rods 45 may be held in place solely by the gripping action of the bends between the panels or may be otherwise fastened therein.

-Having described several modifications of the present invention, it should be apparent to those skilled in the art that the same permits of various modifications in arrangement and detail. All such modifications as come within the scope of the following 'claimsare considered-to be a part of my invention. I l
